To all whom it may concern.'

`Be it knoivnthat I, EniiNMooor'Boi'N- TON, of iVest Newbury, inltlie county of Es sex and'State of li'lassa'chusetts, have invented certain 'new` andr usefulI Improve ments in Railway Frei lit-Cars, ofv which the following is a s iecilication.

This invention re atesto railway freight ears adapted for transporting coal,'gran, gravel, or otherI homogeneous masses.

The invention relates more particularly to cars of the monorail type than to the pi'esent type of ear` adapted for transportation on a pair of rails. y l l The chief objectof the invention is to facilitate loading and unloading of freight of the character above specified, and forlthis reason the car embodying the present invention is'provided with one or more openings in'theroof through 4which Lthe articles of reightmay be introduced, and with discharge -openings inthe floor, and with covers controlling the 'discharge openings by which the discharge'of the freight may be controlled. ffizlv." f

The loadin openingsin the roofof the car are provi ed with separate covers which are adapted to seal the openings tightly and render-them water tight. The flooror bottom wall of the car consists'of horizontal portions'and transversely inclined ortions which divide the lower space of t e Vcompartment into lon itudinal troughs, each trough having a iorizontal bottom wall. The discharge openings are preferably provided in the horizontal portions of the wall, said openings being arranged in longitiidinal series so that they may be covered or iincovered simultaneously by a slide or slides inovalile longitudinally, and provided with openings adapted to register with t-lie openings in the oor of the car. Transversely inclined portions of the floor are inclined in opposite directions and extend upwardly toward each other from the horizontal floor portions. The inclined portions may meet or may be connected by an intermediate portion. In either event they are adapted when so inclined to guide the pieces or particles of freight to the discharge openings and to form and constitute a housing for the tractionwheels. The traction wheels may therefore extend well above. the horizontal planes of the discharge openings,v and the vfloor of to the track upon which the Wheels ro l.

.Of the accompanying drawings which illustrate one form in which the invention may be embodied, Figure 1 represents a top plan view, partly in section, ot a freight car adapted to roll uponv a single rail. Fig. 2 represents a sidel elevation tliereot, partly in section. g Fig. 8 represents an end elevation, -partly in section.

The same reference characters indicate the Asaine parts wherever they occur. The body ofI the oar illustrated comprises side walls 41, a roof or top wall fl and a `floor comprising horizontal portions 42, and transversely inclined portions 48. 'lhe horizontal ortions 42 constitute marginal portionso the iloor and the inclined portions 48` extend'upwardly toward each other at opposite inclinations from the marginal portions. -The meeting edges of the portions 48 may be joined in any suitable way.

The Hoor of the car comprising the aforesaid angular portions divides the lower space of: the compartment into longitudinal troughs,and provides a liousin for the traction wheels 27.' The horizonta marginal portions 42 are provided with discharge openings 49, saidy openings being arranged in longitudinal series as shown by Figs. 1 and 2. ISlidin Vcovers 50 are arranged in the longitudina troughs, said covers being formed with openings 51 which are adapted to registerwit-h the discharge openings 4i), or to be moved out of register with the disehar e openings. As shown by the drawings tie discharge openings 4i) are covered by solid portions of the slides. The slides ISO project through the openings in the end walls of the ear and are connected to operating levers 52. The levers are pivoted at 53 and are arranged to move between lugs 55 aflixed to the end of the car. When the slides are in closed position the levers extend between said lues 55 and are adapted to he locked by pacllocks 56, said padloclcs extending through said lugs.

The side wal s et the car may be rovided with doors such as that indicate( at. 411-. and the end walls may be rovided with doors such as those indicato( 'at 47. '.lhe doors 44 are suspended by wheels 45 rolling upon a guide or track 46.

The roof 4 of the ear is provided with 5S indicates covers for the openings 57,y

said covers having the forni of circular caps. They are provided with segmental keyhole slots 59 of which the enlarged end openings ('0 are adapted to receive flanged studs (il )rejecting upwardly from the annular` iiieiii-y bers in which the openings 5T are formed. The caps or covers 58 are provided with spokes or handles (3Q whereby they may be turned reliitively to the locking studs (il.`

An advantage of constructing a car for handling merchandise of the character named is evident when it isobserved that the merchandise may be conducted to the openings 5T by chutes or other means, and that. the discharge froiiithe car vis effected simply by moving the slides 50 so as to nneover the openings 4t) in the bottom of the car. rlhe loading'and unloading of the car is therefore eil'ected `without requiring handling ofthe merchandise fortraiisporting it in small quantities to and fromithe car.

The car is provided with means `for engaging a guide rail for maintaining the car in an u )right position. The guicerall is indicate( at 20 and is arranged'above-the ear. `The roof 43 of the car supports a plurality of fixtures or brackets such asthat indicated at 34, said brackets being provided with wheels or rolls 35 arranged to embrace the rail Q0. It is proposed to utilize electricity as' the motive force for ropelling the car, or a train of such cars, an( for this reason the guide rail 20 is formed as shown-by Fig. 3. The rail as shown is ofU-shaped cross section` and is inverted so that itis open at the bottom. The railtluis constitutes a housing 'for an electric conductor such as that indicated at 22, t-lie conductor being supported within the rail Q0 by any suitable insulating means. The rail 2O be ing o en at the bottom is adapted to admit a trol cy (not shown) which may be mounted upon the root of the oar to engage the under surface of the conductor 22.

llaving thus ex )lained the nature of my said invention and described a way of construct-ing and using the same, although without atteiii )ting to set forth all of tie forms in whiclh it may be made or all of the modes lof its use, which I claim is 1. Avear for transporting merchandise such as a mass of loose particles, comprising a closed compartment having openings in the top and bottoni walls, rotatable caps for the top openings, interlocking means on the top. wall and on said caps for seaining the caps iii closing position, sliding strips ca eh liiiviiig a series of openings adapted to cover and uncover the openings in said bottoni wall, and means for moving said slides. 2. A railway freight ear comprising wheels, and a body having a iloor consisting of horizontal and transverselyinclined portions dividing the lower space into longitudinal troughs, said bottoni wall having discharge openings, and sliding covers for said openings." 3.' AA monorail freight car comprising wheels, and a body having a floor consisting bfhorizontalmarginal portions and transversely 'inclined portions extendin npwardly toward each other between sai( marginal portions, said wheels` being arranged in thes )ace between said inclined portions, and sli ingstrips extending longitudinally in engagement with said marginal portions, said strips and horizontal portions having openings arranged to be covered and uncovered bylongitudiiial movement of the strips. ln testimony whereof I have ailixed my signature, in presence oi two witnesses.
